LX Cygni: A carbon star is born
S. Uttenthaler, S. Meingast, T. Lebzelter +5
Context: The Mira variable LX Cyg showed a dramatic increase of its pulsation period in the recent decades and appears to undergo an important transition in its evolution. Aims: We…
Lithium destruction and production observed in red giant stars
Stefan Uttenthaler, Thomas Lebzelter, Maurizio Busso +3
According to standard stellar evolution, lithium is destroyed throughout most of the evolution of low- to intermediate-mass stars. However, a number of evolved stars on the red gia…
Constraining the structure and formation of the Galactic bulge from a field in its outskirts. FLAMES-GIRAFFE spectra of about 400 red giants around (l,b)=(0°,-10°)
Stefan Uttenthaler, Mathias Schultheis, David. M. Nataf +3
The presence of two stellar populations in the Milky Way bulge has been reported recently. We aim at studying the abundances and kinematics of stars in the outer bulge, thereby pro…
HERMES high-resolution spectroscopy of HD 149382. Where did the planet go?
V. A. Jacobs, R. H. Østensen, H. Van Winckel +12
A close substellar companion has been claimed to orbit the bright sdB star HD 149382 with a period of 2.391d. In order to check this important discovery we gathered 26 high resolut…
